* keydb.h, keyid.c (hash_public_key, do_fingerprint_md): ... and make a
new one here that shares code with the fingerprint calculations. This
removes some duplicated functionality, and is also around 14% faster.
(Every bit helps).
* import.c (import_one): No longer need the Elgamal import warning.
* getkey.c (get_pubkey_fast): This one is sort of obscure. get_pubkey_fast
returns the primary key when requesting a subkey, so if a user has a key
signed by a subkey (we don't do this, but used to), AND that key is not
self-signed, AND the algorithm of the subkey in question is not present in
GnuPG, AND the algorithm of the primary key that owns the subkey in
question is present in GnuPG, then we will try and verify the subkey
signature using the primary key algorithm and hit a BUG(). The fix is to
not return a hit if the keyid is not the primary. All other users of
get_pubkey_fast already expect a primary only.
don't know the structure of by using the opaque MPI.
(do_fingerprint_md_sk): We cannot calculate the fingerprint from a secret
key unless we know the structure (since we can't leave off the secret key
parts), so fail early..... (keyid_from_sk, fingerprint_from_sk): .... and
return all zeroes.
keydb.h, keyid.c (namehash_from_uid): New function to rmd160-hash the
contents of a user ID packet and cache it in the uid object.
* keylist.c (list_keyblock_colon): Use namehash in field 8 of uids. Show
dates for creation (selfsig date), and expiration in fields 6 and 7.
* trustdb.c (get_validity, get_validity_counts, update_validity): Use new
namehash function rather than hashing it locally.
